PROBLEM TO BE SOLVED: To provide a pump container to be used so that buckling of a container main body is not brought by the pressing-down force in the pumping operation even when the container main body is formed into the thin wall to reduce the weight. SOLUTION: The pump container is provided with a dip tube with its end set on the lower section of the pump main body and extended toward the bottom of the container main body, and a plurality of slits are formed to extend from the end of the container bottom side of the dip tube, and the end of the dip tube is expanded outwardly while being slidably brought into contact with the container bottom owing to the pressing force when the pump main body is mounted on an opening of the container main body.
